The Endless Archive - Entrance

The Endless Archive is a sprawling demiplane and library linked to Apocrypha.

A portal to the Endless Archive can be found north of Runemaster's Acropolis, inside a cavern that can be accessed on the shoreline. Alternatively, it can be accessed by clicking on the icon on the Apocrypha map and teleporting directly to the Archive.

Functionality

The Endless Archive is an "endless" dungeon/duo-arena added in Update 40. The Endless Archive does not have a normal or veteran mode; it gets progressively more difficult with each 'round' one completes. Players may enter solo, with an NPC Companion or with one friend (in a duo). There is a separate Leaderboard for solo and duo completions of the archive.

What makes The Endless Archive different from other PvE content in ESO is that the majority of its encounters are randomly generated. Each 'round' consists of randomly selected trash packs, which can conjure up unusual combinations of various mobs from throughout the game, such as bone colossi fighting alongside dwarven automata. There are two such waves prior to the third and final segment of each round.

A round's final encounter spawns a Boss, again, randomly selected from dungeon, world, and trial content throughout ESO, including Expansions. The bosses’ HP and damage are reduced, making them more suitable for a 1 or 2 player battle. However, they do retain most of their original mechanics, so knowledge and experience of a wide range of bosses in ESO is advantageous to have.

Solo, Duo, Companions

While The Endless Archive is neither normal nor veteran, the ramping difficulty is static regardless of whether you play solo or as a duo. A player may certainly last longer and complete more rounds playing with another player. Companions are available to select within the Archive, however, they are unable to make choices based on content and therefore are not the best at staying alive as difficulty increases.

• Best method: Duo with a friend.
• Nominal: With a Companion (and a quick rez).
• Challenging: Solo. One must have a solid 'solo build' as well as in-depth knowledge of game mechanics.

Progression

The Endless Archive is broken down into smaller portions to make it more structured and manageable:

• Stages – Each time you go through a Portal in the Endless Archive, you are taken to a new Stage. You usually have two stages of trash mobs, each one containing three packs of randomly generated mobs. The third stage will contain a boss, randomly selected from a very long list of potential bosses found throughout ESO.
• Cycles – After beating the boss at the end of the final stage, you will begin a new Cycle. Each cycle has the same structure as that described above, two stages and a boss fight on the final one.
• Arc – After completing four Cycles, you will have to fight another boss, which is the final boss of the Arc. This one is tough and can easily end your run. After completing the boss, you will move onto another Arc, beginning the process anew (Arc 2, Cycle 1, Stage 1). Each Arc is more difficult than the last – mobs and bosses will hit harder and you may occasionally find surprise bosses (Marauders) mixed in with the trash pulls.

1 Arc consists of the following:

Cycle 1	Cycle 2	Cycle 3	Cycle 4	Cycle 5
Trash	Trash	Trash	Trash	Trash
Trash	Trash	Trash	Trash	Trash
Boss	Boss	Boss	Boss	Big Boss

† This may have been reduced now to 3 Cycles only.

Visions and Verses

Verses are temporary buffs that last until the end of the next stage.
Visions are permanent buffs that will be on your character until you finish the Endless Archive.

• Verses
  • Offensive Verses
  • Defensive Verses
  • Utility Verses

  • Offensive Visions
  • Defensive Visions
  • Utility Visions

Rewards

After completing a Cycle, Arc or side puzzle, a Muniment Chest will be awarded, containing a variety of rewards including gold, equipment, soul gems and a special new currency called Archival Fortunes.

Archival Fortunes can be spent at the merchants in the entrance area of the Endless Archive in return for special rewards, such as Monster Mask style motifs, Legendary quality treasure maps, non combat pets, Companion gear and more..

The Endless Archive item sets are Class-specific. A player will typically only find pieces of the set for the class currently being played. As with all curated Sets, once the 'Stickerbook' is completed, other set pieces for other classes will begin to drop.

Enemies

Normal & Elite

The enemies that spawn while with the Endless Archive are randomised with each stage. However, a selection from 1-2 "Factions" will be spawned by the maligraphies for each non-boss stage. Some of the creatures that spawn are independent of any factions, such as the Dremora and Fabled enemies. The latter appear more frequently in later arcs and are more powerful than most.

Please note, most of these listed factions correspond to the categories mentioned for the Archive's Most Adored achievement.

Bosses

There are many different bosses one can potentially find in the The Endless Archive. These bosses are reflections of dungeon, world and trial bosses throughout ESO, and typically retain most of their mechanics and attacks, however their health and damage is scaled down to make them more balanced for 1 or 2 players.

As one progresses through The Endless Archive, bosses will get tougher, with more hitpoints and damage. Optimise a build for the Endless Archive with the following Penetration table:

The armour of bosses in Endless Archive is as follows:

Boss	Pen Req'd
First Boss:	9100
Second Boss:	9100
Third Boss:	9100
Fourth Boss:	9100
Arc Final Boss:	18200

This pattern will repeat in subsequent Arcs after the first one.

Boss List

There are many bosses that can appear, from story quests bosses, dungeon bosses, trial bosses, and world bosses. You do not have to have previously encountered a boss in other areas of the game for it to appear in the Endless Archive.

The Marauders do not appear in the boss stage, but can appear randomly in any other stage after Arc 1.

Leaderboard

The Endless Archive has several leaderboards where players can compete against each other. These scores are NOT time dependent, as each player or team will work through the dungeon arcs at different paces. Score is improved by completing more stages, cycles and arcs. Solo and Duo Leaderboards are separate. Having a Companion active upon entering the Archive will place the player in the Duo Leaderboard if they score well.
